Restore underground dog-fence continuity in minutes with the PetsTEK Waterproof Wire Splice Kit. Each kit pairs a medium-size wire nut with a PVC tube pre-filled with proprietary waterproof gel. Simply strip the wire of insulation, twist wires together inside the nut, push the connection into the tube, and let the gel overflow to create a permanent, corrosion-proof seal that can be buried immediately. These connectors fit 12-, 14-, 16-, 18- and 20-gauge solid copper wire compatible with PetSafe, SportDog, Dogtra and most competing in-ground fence systems. The durable UL-listed components resist UV exposure, soil acidity, lawn-mower vibration and seasonal temperature swings, delivering years of worry-free containment. Not just for pet fencing—use PetsTEK splices on landscape lighting, irrigation valves, pathway lights and other low-voltage outdoor projects that demand a watertight, direct-bury connection. Proudly engineered and manufactured in the USA for professional-grade reliability.
